Congressional Budget Office Cost Estimate: S. 1589, Damon Paul Nelson and Matthew Young Pollard Intelligence Authorization Act for Fiscal Years 2018, 2019, and 2020 [open pdf - 234KB]
From the Bill Summary: "S. 1589 would authorize appropriations for fiscal years 2019 and 2020 for intelligence activities of the U.S. government, including the Intelligence Community Management Account and the Central Intelligence Agency Retirement and Disability System (CIARDS). The bill also would modify the security clearance process for federal agencies, expand personnel benefits for employees of the intelligence community, and create or modify other intelligence programs. [...] CBO [Congressional Budget Office] estimates that implementing the unclassified provisions of the bill would cost about $6.1 billion over the 2020-2024 period; that spending would be subject to appropriation of the specified and estimated amounts. In addition, several provisions of the bill would increase and decrease direct spending; therefore, pay-as-you-go procedures apply. CBO estimates that the bill would increase net direct spending by $10 million over the 2020-2029 period. Enacting the bill would not affect revenues. CBO estimates that enacting S. 1589 would not significantly increase net direct spending or on-budget deficits in any of the four consecutive 10-year periods beginning in 2030. S. 1589 would impose an intergovernmental mandate, as defined in the Unfunded Mandates Reform Act (UMRA), on state, local, and tribal governments, but CBO estimates that it would impose no duty on those governments that would result in additional spending or a loss of revenues."
